SPECIFICATION forming part of Letters Patent No. 265,934, dated October 10, 1882.

Application filed July 19, 1882. (No model.)

To all rwhom zt may concern.-

Beit known that I, JAMES L. Nonuls, a citizen ofthe United States, residing at Washington, in the District of Columbia, am in posses- 5 sion ot' an invention for a new and useful Improved Composite Gun, invented by WILLIAM PALLIsER, deceased, ot' which the following is a specification.

This invention relates to an improved con- 1o struction of heavy guns Withun outer casing ot' cast steel andan inner lining nt' coiled wrought-iron and steel, as shown on the accompanying drawing, which shows a longitudinal section of the gun.

15 The outer casing,C C', is formed ot' two separate steel castings, screwed together at C2. rIbis casing is turned and then annealed t-o equalize the strains, and then has the internal screw-thread cut therein for the. reception of zo the coiled wrought-iron lining-tube B. The lining-tube A, which may either be ot' coiled wrought-iron or of steel, is then first inserted from the breech end, andis secured at the muzA 4zie by the screw-collnr'P 'in a similar manner 25 to thatdescribcd inthe patents of William Palliser, after which the tube B is screwed in until Y its shoulders bear against the shoulders of the casio g C, and it is then secured in position by thetubular breechqiilng D. The tube, as also 3o' the A tube, when of coiled wrought-iron, are

made to fit easily into the casing, being expanded by the pressure on firing so as to lit the casing closely.

The gun is here shown as a breech-loader, the movabl breech-plug F being carried by 35 the hinged collar G and screwed in and out in a well-known manner. When used as a muzzle-loader the end of the B-tube-weuld be closed by a cup-shaped plug screwed into n.1' and behind thisa second plug would be screwed 4o into the tubular plug D.

Having thus described the nature of thisinvention and in what manner the same is to be performed, I claim- A composite gun consisting' of a cast-steel 45 outer casing, C C', formed in two parts screwed together, in combination with a front liningtube, A,ot'eithercoiled wrought-iron orofsteel, and a rear liningnube, B, of coiled wroughtiron screwed into the casing fromfthe breech, 5o substantially as described..

In testimony whereof I have signed my naine to this specification before two subscribing witnesses.
